ABSTRACT

Entre 2017 y 2018 se realizaron muestreos durante cuatro meses en un fragmento de bosque tropical perennifolio de un área natural protegida de Chiapas, México. Se instalaron trampas de caída ubicados a lo largo de un trayecto de aproximadamente 500 m. Las trampas fueron cebadas con individuos recién muertos de Messicobolus magnificus, un milpiés abundante en la reserva durante la temporada lluviosa. Se capturaron 108 individuos de cuatro especies de escarabajos: Canthon vazquezae (92), Deltochilum pseudoparile (13), Coprophanaeus corythus (2) y Ateuchus rodriguezi (1). Únicamente D. pseudoparile ha sido previamente recolectada con carroña de otras especies de milpiés. El uso de este tipo de recurso posiblemente sea una fuente alterna que permite reducir la competencia interespecífica por otros recursos efímeros entre los Scarabaeinae.


Between 2017 and 2018, samplings out for four months in a tropical evergreen forest fragment from a natural protected area of Chiapas, Mexico, were carried. Pitfall traps were installed along a path of about 500 m. The traps were baited with freshly killed individuals of Messicobolus magnificus, an abundant millipede during the rainy season in the reserve. 108 individuals of four beetles' species were captured: Canthon vazquezae (92), Deltochilum pseudoparile (13), Coprophanaeus corythus (2) and Ateuchus rodriguezi (1). Only D. pseudoparile has been previously collected with carcasses from other millipede species. The use of this resource type is possibly an alternative source that reduces interspecific competition among the Scarabaeinae for other ephemeral resources.
